L2720W
Low drop dual power operational amplifiers
Features Output current up to 1 A Operates at low voltages Single or split supply Large common-mode and differential-mode
range Low input-offset voltage Ground compatible inputs Low saturation voltage Thermal shutdown Clamp diode
Description
The L2720W is a monolithic integrated circuit in
SO16 (Wide) package, intended for use as a
power operational amplifier in a wide range of
applications including servo amplifiers and power
supplies.
It is particularly suitable for driving coils, inductive
loads and for use in motors.
The high gain and high output power capability
provide superior performance whenever an
operational amplifier/power booster combination
is required.
